Central Polygraph Service utilizes state-of-the-art digital polygraph systems and conducts polygraph examinations according to strict standards and methods as approved and accepted by the American Polygraph Association and the U.S. Federal Government. Due to established laws, there is a strict limit of up to (4) pertinent test questions that may be established by the client for each polygraph examination (all other questions on the polygraph test are generic in nature and are established by the examiner for baseline purposes). Although each polygraph examination is always customized per the client’s needs and requests, following is a sample list of just some of the types of approved pertinent test questions that are frequently used for employee theft type examinations:


  • Did you take any of that missing $10,000 from ABC Co.?

  • Did you remove that computer-chip schematic diagram from the ABC Co. premises?
